Yes, thanks. What I was confused by was actually when the struct is defined
inside the unittest with the static keyword - pure is not inferred. Non-static
nested struct inference works, it seemed weird that adding static prevents
inference. But obviously the compiler treats it the same as the code in comment
0.
